Looks like OpenCL is properly loaded. To better analyse the slow
response time of your system run with 'darktable -d opencl -d perf'.
After each processing step you get profiling output. For the start only
look at lines like
17,607291 [dev_process_image] pixel pipeline processing took 0,212 secs
(1,374 CPU)
You will see the same output if you switch off OpenCL so this should
give you a first estimate on how strong the GPU is able to boost
performance on your system. Note that you need to activate some of the
more demanding modules to really see a difference. Try for example
profiled (denoise).

My output looks much the same as yours and Michael's. So I am now
convinced that I was wrong putting the blame for my DT's shortcomings to
openCL.
There seems to be some flaw in the graphics. But the output concerning
the graphics card looks ok:

I think I should either reinstall DT or start a new subject request. Or
do you have an idea?
